YouTube Summarizer AI - Recap & Chat

YouTube summarizer with AI summaries, timestamped chapters, video chat, and Markdown export.

YouTube Summarizer AI turns long videos into accurate, source-grounded notes in seconds. Open any YouTube video, click Summarize, and get a clear TLDR, key points, clickable timestamped chapters, and chat answers based on the full transcript. No login is required for the free plan, and failed summaries never consume your daily quota. 🚀 🚀 Why this YouTube summarizer is different Most AI video tools are fast until they are wrong. They summarize the title, skip important details, fail on auto-generated captions, or hide useful features behind a signup wall. This extension is built around the complaints users keep repeating about existing YouTube summary tools: shallow summaries, broken transcript fetches, missing timestamps, long-video truncation, forced login, and confusing credit limits. YouTube Summarizer AI starts with the full transcript available to your browser, including auto-generated captions when YouTube provides them. Long transcripts are sent to our backend for chunked AI summarization so the output is based on what was actually said, not a guess from the title. The result is structured for skimming, studying, research, and content workflows. ⚡ Everything in the free plan ✓ 4 full summaries per day, forever ✓ No signup before your first summary ✓ TLDR, key points, and timestamped chapters ✓ Click any chapter timestamp to jump to that exact moment in the video ✓ Copy or download the summary as Markdown ✓ 3 chat-with-video questions per day ✓ Works with manual captions and YouTube auto-generated captions ✓ Failed, empty, or unavailable transcripts never decrement quota ✓ Clean in-page panel that fits YouTube instead of covering the video ✓ Local summary history for your recent videos 🔓 What Pro unlocks ✦ Truly unlimited summaries with no credit games ✦ Long videos, lectures, podcasts, interviews, webinars, and 3 hour deep dives ✦ Unlimited chat with the video, grounded in the transcript ✦ Summary language control for multilingual study and research ✦ Source-style timestamp citations for easier verification ✦ Priority processing for heavy transcripts ✦ All future export and workflow features as they ship 📌 Built to solve the real complaints Accuracy: summaries are generated from the transcript, not the title. Reliability: the caption extraction runs in the YouTube page context and uses the same session your browser uses. Timestamps: every chapter has a clickable time so you can verify the point in the original video. Long videos: transcripts can be chunked before synthesis instead of getting cut off. Free tier: useful by default, with plain limits and no hidden credit drain. Privacy: only transcript text needed for the requested summary is sent to our backend. 🎯 Who it is for Students use it to turn lectures, tutorials, and conference talks into study notes. Researchers use it to scan long interviews and jump straight to relevant moments. Marketers use it to pull content ideas from podcasts and webinars. Founders use it to digest product videos, customer calls posted to YouTube, and competitor demos. Writers use it to turn a video into a structured outline before drafting. Anyone who watches educational or business videos can save time without losing the context that matters. 🛠️ How it works 1️⃣ Open a YouTube video with captions or auto-generated captions. 2️⃣ Click the Summarize button on the page or open the toolbar popup. 3️⃣ Choose your summary mode: Quick scan, Balanced, Study notes, or Action items. 4️⃣ Read the TLDR, key points, and chapters. 5️⃣ Click a timestamp to jump to the source moment, ask follow-up questions, or export the notes. 💡 Real use cases → Summarize a 90 minute podcast before deciding whether to watch it fully → Turn a software tutorial into step-by-step notes → Pull timestamped chapters from a product demo → Ask a lecture video where a topic was explained → Export a Markdown summary to Notion, Obsidian, Google Docs, or your research folder → Convert a video in another language into notes you can actually study → Build a reading list from a playlist without watching every minute → Verify any important claim by jumping back to the timestamp 🔒 Privacy you can understand When you request a summary or chat answer, the extension sends the transcript text, video title, video ID, target language, and anonymous device ID to our backend at peakproductivity.online. The transcript is used only to generate the requested summary or answer. We do not sell transcript data. We do not inject ads. We do not collect browsing history. Stripe handles payments if you upgrade, and SendSimple handles the optional email checklist if you choose to subscribe. You can use the free tier without an email address. 🆚 Why choose this instead of the alternatives ✓ vs title-only summaries: this AI YouTube summary uses the actual transcript ✓ vs tools that break on captions: this extension reads captions in the page context whenever YouTube exposes them ✓ vs forced-login tools: your first summary works without creating an account ✓ vs credit systems: Pro is flat unlimited, and free failures never count against you ✓ vs wall-of-text tools: the output is structured as TLDR, key points, chapters, chat, and export ✓ vs clashing overlays: the panel is compact, readable, and built for repeated use 🛡️ Security Manifest V3. No remote JavaScript. No eval. No hidden tracking libraries. The extension requests only the permissions needed to read the active YouTube page after you ask it to summarize, store your settings and quota locally, and contact the Peak Productivity backend for summaries, license checks, and optional growth events. ❓ Frequently asked questions Does it work on videos without captions? It works when YouTube provides manual captions or auto-generated captions. If a video has no transcript available at all, the extension tells you clearly and does not charge your free quota. True audio transcription fallback is planned for a later version. Does it summarize long videos? Yes. The backend is designed for chunked transcript processing so long lectures, podcasts, and webinars do not get truncated like simple prompt-copy tools. Can I ask questions about the video? Yes. The chat feature answers from the transcript context. Free users get a few questions per day, and Pro unlocks unlimited video chat. Is this a video downloader? No. This extension summarizes transcript text. It does not download, stream, or cache YouTube audio or video. Is the free plan useful? Yes. You get 4 full summaries per day, Markdown export, timestamped chapters, and 3 chat questions. No signup is required. What is the difference between Free and Pro? Free is for regular daily use. Pro is for heavy users who summarize many videos, handle long podcasts and courses, need unlimited video chat, and want flat pricing with no credits. 🚀 Get started Install YouTube Summarizer AI, open a video, and click Summarize. In less time than it takes to scrub through the intro, you will have a useful YouTube summary with clickable chapters, key points, and export-ready notes.
